When the housing pieces 322 a, 322 b are pushed together, theresilient cantilever arms 332 flex outwardly, with the assistance oframp surfaces 338, as theretaining tabs 336 enter theexterior slots 337. When theretaining tabs 336 move past the retainingshoulders 334, the inherent elasticity of thecantilever arms 332 causes thecantilever arms 332 to snap into a locked position. In the locked position, theretaining tabs 336 oppose or engage the retainingshoulders 334 to prevent the housing pieces 332 a, 332 b from being disconnected. If it is desired to disconnect the housing pieces 332 a, 332 b, thecantilever arms 332 can be manually flexed in an outward direction thereby allowing the housing pieces 322 a, 322 b to be pulled apart. - As used herein, the phrase “snap-fit connection” means a connection provided by a resilient member that flexes or deforms past a retaining structure and moves to a locking or retaining position by the inherent flexibility or elasticity of the resilient member. In the above described embodiment, the
arms 332 move or “snap” past theshoulders 334 by the inherent bias of thearms 332. The term snap-fit connection is not limited to resilient arms, but includes any structure (e.g., bumps, tabs, shoulders, etc.) that are deformed during insertion and move to a retaining position by the inherent elasticity of the structures. In other embodiments, the housing pieces 322 a, 322 b can be coupled together by other types of connection techniques such as press-fit connections or adhesive connections. - The complementary relationship between the interior of the
housing 320 and thehousing mount 306 of thebulkhead 300 is preferably configured to prevent relative rotation between thehousing 320 and thebulkhead 300. The complementary shape of the interior of thehousing 320 andhousing mount 306 also prevents thehousing 320 from being axially slid from thebulkhead 300. - The
housing 320 of the connector preferably includes structure for providing a snap-fit connection between theconnector 150 and a piece of telecommunications equipment (e.g., a jack module or a panel such aspanel 120 shown in FIG. 5). As shown in FIGS. 1, 2 and 5, thehousing 320 includes top and bottomresilient cantilever arms 360. As best shown at FIG. 2, eachcantilever arm 360 includes first and second retainingtabs gap 366. Thesecond tab 364 is located at the free end of thearm 360, and thefirst tab 362 is located between thesecond tab 364 and the base end of thearm 360. Thefirst tab 362 includes a ramp surface 362 a and thesecond tab 364 includes aramp surface 364 a. As best shown in FIG. 5, the ramp surfaces 362 a and 364 a converge as the ramp surfaces extend toward thegap 366. For example, as shown in FIG. 5, thesurfaces 362 a, 364 a of theupper arm 360 both angle upwardly as thesurfaces 362 a, 364 a extend toward theircorresponding gap 366, and thesurfaces 362 a, 364 a of thelower arm 360 both angle downwardly as thesurfaces 362 a, 364 a extend toward theircorresponding gap 366. - Referring still to FIG. 5, the
tabs gap 366. The retaining surface 362 b has a smaller vertical dimension d1 than a vertical dimension d2 of the retaining surface 364 b. As shown in FIG. 5, the top andbottom tabs 364 define a height h1 that is greater than a height h2 defined at afront end 341 of thehousing 320. Preferably, the height h1 is greater than any other height defined between thetabs 364 and thefront end 341 of thehousing 320. The top andbottom tabs 362 define a height h3 that is greater than a height h4 defined at arear end 343 of thehousing 320. Preferably, the height h3 is greater than any other height defined between thetabs 362 and therear end 343 of thehousing 320, but is smaller than the height h1. As described below, this configuration allows theconnector 150 to be inserted into a mounting location from either a forward or a rearward direction. - Referring to FIGS. 4 and 5, the
connector 150 is adapted to be mounted in anopening 119 defined by a piece of telecommunications equipment such aspanel 120. Referring to FIG. 5, theconnector 150 can be inserted into the opening 119 from either afront side 121 or arear side 123 of thepanel 120. To mount theconnector 150 from thefront side 121, therear end 343 of theconnector 150 is inserted in a rearward direction through theopening 119. As theconnector 150 is pushed through theopening 119, the ramped surfaces 362 a oftabs 362 engage upper and lowerfront edges 357, 359 of theopening 119 causing thearms 360 to flex inwardly toward one another. Once thetabs 362 move completely through theopening 119, thecantilever arms 360 snap outwardly by their inherent elasticity such that thepanel 120 is trapped within thegap 366 between the retaining surfaces 362 b, 364 b of thetabs front side 121 of thepanel 120, and the retaining surface 362 b engages or opposes therear side 123 of thepanel 120. By flexing the cantilever arms inwardly while pushing theconnector 150 in either a forward or rearward direction, theconnector 150 can be removed from theopening 119. - To mount the
connector 150 from therear side 123, thefront end 341 of theconnector 150 is inserted in a forward direction through theopening 119. As theconnector 150 is pushed through theopening 119, the rampedsurfaces 364 a oftabs 364 engage upper and lowerrear edges opening 119 causing thearms 360 to flex inwardly toward one another. Once thetabs 364 move completely through theopening 119, thecantilever arms 360 snap outwardly by their inherent elasticity such that thepanel 120 is trapped within thegap 366 between the retaining surfaces 362 b, 364 b of thetabs front side 121 of thepanel 120, and the retaining surface 362 b engages or opposes therear side 123 of thepanel 120. - In the depicted embodiment, the top and bottom sides of the housing are shown having identical configurations. However, in other embodiments, different snap-fit configurations can be provided on the top and bottom sides of the connector. Further, in some embodiments, only one snap-fit structure may be provided. It will be appreciated that the snap-fit structure could be provided on the top, the bottom or either side of the
